Mine too is on Wear 2.17, and Play Services 14.7.99. The Bluetooth is occasionally unstable but readily reconnects. The WiFi occasionally disconnects, however it seems to be staying connected during attempted QR code retrieval. Amazingly, the Facer folks have remained relatively quiet on this major issue. I’m not sure if the code retrieval is via WiFi, or over Bluetooth via the phone. If it is via Bluetooth, that would explain why there might be differences between the Android and IOS platforms with watches still having essentially the same software.
